Hi,
Espressif released the official V4.1 release of ESP-IDF just 2 days ago. Unfortunately they made a change that breaks compatibility with the latest VisualGDB toolchain available. The new toolchain requires a different command line argument and the release make files expect the new argument to be there.
See https://github.com/espressif/esp-idf/releases for more information (search for esp-2020r2)
Any attempt to build for the new release produces:
Error unrecognized command line option '-mfix-esp32-psram-cache-strategy=memw'; did you mean '-mfix-esp32-psram-cache-issue'?
This only came out 2 days ago but I am hoping that a new toolchain that is compatible with this breaking change will soon be available. Or perhaps you can suggest a work around. Unfortunately I really need a fix that was first introduced in this build of ESP-IDF.
Thanks,
Don
